The oik-bbpress plugin is only needed on sites that implement bbpress.
The current version doesn’t do much at all. Below is the ‘effective’ code.
* bbPress does not cater for shortcode expansion in titles so we need to apply a filter when
* the title is being used in a text= attribute
add_filter( 'bbp_get_forum_title', 'bw_strip_tags' );
From oik version 1.17 the oik-bbpress plugin becomes a standalone plugin supported from oik-plugins. Download oik-bbpress-strip-tags-from-bbpress-forum-title-tooltips version 1.18
